Benchmark: Field formatting

Script Preparation code:

var field = "event_data.param.parms[0]['hello']"

Tests:

regex
// replaces the start of the string with "['", if it starts with "[" str = field.replace(/^(?!\[)/, "['") // replaces the end of the string with "']", if it does ends with "]" .replace(/^(?<!\])(.*)(?<!\])$/, "$1']") // replaces the middle dots with "']['" if there is not "]" before the dot and no "[" after the dot .replace(/(?<!\])(?<=[^\]])\.(?=[^\[])(?!\[)/g, "']['") // replaces all "]." with "]['" .replace(/\]\./g, "]['") // replaces all ".[" with "'][" .replace(/\.\[/g, "'][") // replaces all "[" that are in the middle of the string, if there is no "]" before it .replace(/(?<=[^\]]+)\[(?=[^\[]+)/g, "']["); return str;
loops
if (field.startsWith('[')) { return field; } else { let arr = field.split("."); let newStr = ""; for (let i = 0; i < arr.length; i++) { if ( arr[i].includes('\[') ) { let [first, ...rest] = arr[i].split('['); rest = rest.join(''); newStr += `[\'${first}\'][${rest}`; } else { newStr += `[\'${arr[i]}\']`; } } return newStr; }
